A court decision deeming four videos by the feminist protest group Pussy Riot as extremist has come into force.

The Moscow City Court refused on January 30 to consider an appeal to the ruling.

The court decided that Yekaterina Samutsevich, who filed the appeal, is not eligible to challenge the decision as she was not a participant in the original hearing that designated the video as extremist in November.

One video showed an illegal performance in February 2012 at Moscow's main Russian Orthodox Cathedral that protested President Vladimir Putin's rule.

It led to the arrest of three members of the group.

Two of them -- Maria Alyokhina and Nadezhda Tolokonnikova -- are now serving two-year prison sentences for "hooliganism motivated by religious hatred."

Samutsevich received a suspended sentence.

The Zamoskvorechye District Court in Moscow ruled in November that access to all websites hosting the videos must be limited.

According to the court's decision, websites that do not remove the Pussy Riot videos will face administrative penalties, including fines up to 100,000 rubles ($3,000).
